PCI: Add helper macro for pci_register_driver boilerplate (aad4f400) · Commits · 戴 / test

This patch introduces the module_pci_driver macro which is a convenience macro for PCI driver modules similar to module_platform_driver. It is intended to be used by drivers which init/exit section does nothing but register/unregister the PCI driver. By using this macro it is possible to eliminate a few lines of boilerplate code per PCI driver. Based on work done by Lars-Peter Clausen <lars@metafoo.de> for other busses (i2c and spi).
